The home-made device of EGaIn set-up is applied to study the characteristics of molecular tunneling through self-assembled molecule.

A thermoelectric test platform based on the EGaIn test technology was built. The temperature difference was generated by heating the electrodes, and the potential difference between the two electrodes was measured to obtain the Seebeck coefficient of the molecule. Among them, the Micro-syringe, Au electrode, and tungsten needle constitute the measurement loop, and the micro-operation table is used to adjust the position of the Micro-syringe. The enlarged image on the right shows the EGaIn Tip and its mirror image.
